LUBBICATOR.

SPECIFICATION forming part of Letters Patent N0. 755,898, dated March29, 1904.

Application filed March 24, 1903.

To all whom it may concern.-

Be it known that I, HEINRICH LUDENDORFF, a subject of the King ofPrussia, German Emperor, andaresident of Berlin, in the Kingdom ofPrussia, German Empire, have invented a certain new and usefulImprovement in Lubricators,of which the following is a specification.

My invention relates to improvements in lubricators having a pistonwhich is advanced by clockwork or wheel-gearing to eject the lubricant;and the objects of my improvements are to provide means for regulatingthe quantity of lubricant ejected in a given time and to render thepiston ejecting the lubricant visible. I attain these objects by theconstruction illustrated in the accompanying drawings, in which Figure 1is a plan of a portion of the mechanism of a lubricator adapted to besecured to some moving part of a machine or the like and to be actuatedby the inertia of a weighted lever. Fig. 2 represents a side elevationand partial section of the same lubricator. Fig.

. 3 is a plan showing another construction of the driving part of theclockwork or other gear. Fig. 4 shows a section on the line a a of Fig.3. Fig. 5 is a plan of a lubricator adapted to be secured to a fixedpart of a machine and to be regulated by a balance-wheel or spring. Fig.6 shows a side elevation of the lubricator illustrated in Fig. 5.

My lubricator comprises a vessel 1', on which is disposed a casing 2,which contains mechanism 4 for advancing the piston 3 in the vessel 1.In the construction shown in Figs. 1 to 4 the mechanism 4 is adapted tobe driven by the inertia of a weighted part 5, While in the constructionillustrated in Figs. 5 and 6 a spring and balance-wheel are provided forthe purpose. The inertia of a Weighted part is utilized for actuatingthe type of lubricators used for lubricating the moving parts of amachine, such as the connecting-rod head of a steam-engine, while thespring and balance-wheel form the actuating or driving means of themechanism of stationary lubricators. The weighted lever 5, Fig. 1, isturned by inertia about the spindle 7 when the part to which thelubricator is at- 5 tached is moved. On the spindle 7 is secured SerialNo. 149,275. (No model.)

a ratchet-wheel 8,- which is turned by the pawl attached to the weightedpart 5. In order to limit the movement of the weighted part, a pin'lOand an eccentric disk or stop 11 are provided, which latter is fixed toa spindle 12, provided with an index 13, adapted to move over a scale onthe outside of said casing. The eccentric disk or stop has a number ofsteps 15, which on turning the disk increase or decrease the amplitudeof the oscillation of the weighted part 5. In this way the movement ofthe ratchet-wheel 8 is regulated so that the feed of the lubricant canbe adapted to requirements.

In the modified construction shown in Fig. 3 the weighted part 5 isadapted to slide in a guide 9. An arm extends from said weight through aslot in the guide 9 and carries a pawl, which is kept by a spring inengagement with the ratchet-wheel 8. The eccentric disk 11, according toits angular position, limits the stroke of the weighted part 5 more orless.

For stationary lubricators the stop 11 is adapted to limit the movementof the balance- Wheel. A pin 16 is for this purpose secured to thebalance-wheel, which strikes against the inclined surface 15 of thestop, so that the speed of the escapement-wheel will be alteredaccording to the position of the stop 11.

The position of the piston 3 in the vessel 1 can be seen through thesight-glass 17, which consists of a strip of celluloid or othertransparent substance held by a frame 18 and renderedtight by suitablepacking.

What I claim, and desire to secure by Letters Patent, is

1. Lubricator comprising in combination av vessel adapted to contain alubricant and having an outlet, a casing adjacent to said vessel, apiston in said vessel, wheel-gearing in said casing adapted to advancesaid piston and displace the lubricant through the outlet of said vessela movable weighted body in gear with said wheelgearing, and anadjustable stop having inclined surfaces and adapted according to itsposition to limit the stroke of said weighted body, substantially as setforth.

2. Lubricator comprising in combination a vessel adapted to contain alubricant and having an outlet, a casing adjacent to said vessel, apiston in said vessel, wheel-gearing in said casing adapted to advancesaid piston and displace the lubricant through the outlet of said vessela movable weighted body in gear with said wheel -gearing, and anadjustable stop having inclined surfaces and adapted according to itsposition to limit the stroke of said weighted body, an index connectedto said stop, and a scale over which said index moves I0 substantiallyas set forth.

In witness whereof I have hereunto signed my name, this 12th day ofMarch, 1903, in the presence of two subscribing witnesses.

HEINRICH LUDENDORFF.
